staging: comedi: ni_65xx: remove board() helper function 

This local helper function is a duplicate of the comedi core
privided comedi_board() helper. Use that function instead and
use a local variable to hold the boardinfo pointer instead of
calling the helper each time the boardinfo is accessed.
